Your joints enable you to enjoy movement, with the primary function of holding the skeletal structure of your body together. Simply stated, the joint relies on cartilage to act as a cushion between the adjoining bones. Maintaining normal, healthy joints should be a lifelong goal achieved by adopting a healthy lifestyle. Elements of healthy living that help maintain healthy joints include sustaining a healthy body weight, participating in regular and appropriate exercise, and maintaining a nutritious and healthy diet. Cartilage Formula is formulated to provide clinically and nutritionally significant amounts of the nutrients essential to normal cartilage maintenance, strength, and function. Cartilage Formula contains a significant amount of glucosamine HCI (1,500 mg) as dictated by human clinical studies.
